Gen 3 Shimano Ultegra R8000 Single Leg Power Meter Crank Arm

Finding time to train can be trying in a world of 9-to-5 work life, family, and long commutes —not to mention wanting to have a well-rounded existence between friends, hobbies, and fitness. This juggling act can make finding the hours to train trying, so its important that you get the most out of what little time you may have. With the Stages Cycling Shimano Ultegra R8000 Single Leg Power Meter Crank Arm you'll find all of the data you want, without the price tag that destroys your annual upgrade budget, so you can push yourself harder to reach for gains. It collects data with its easy to install left-leg power meter to deliver tangible information and reliable numbers to improve your ride, and overall fitness.

The key behind this crank arm is the little power meter pod affixed to its inner face, which takes what originally was a standard Ultegra 8000 crank arm to the next level and adds the ability to gather pinpoint power data to better measure your ride. It utilizes a blend of strain gauges and an accelerometer to gather position and force data 64 times per second and deliver power readings with a claimed +/- 1.5% accuracy, half a percent more accurate than previous models, and right in line with what we'd expect from any quality power meter.

For the gram counters out there, the Stages meter adds a minuscule 15 grams to the crank arm, which is a tiny concession to gain the massive data tracking and training specificity having a power meter affords. To put it in perspective, choosing the smaller safety pins the next time you don a race number should easily balance things out. This crank runs off of a coincel battery, offering up to 200-hours of battery life. Since the meter sits externally on the crank it's easy to swap mid-season without tools. The meter its self is well encased, earning an IPX7 waterproof rating to give you peace of mind if a storm breaks out on race day. When stormy weather rolls in, or the changing seasons cause the temperature to fluctuate, you'll be happy to find that the power meter has active temperature compensation to continually calibrate to the dropping and rising mercury on your ride, continuing to provide you with accurate data.

Stages PM for Ultegra

Familiarity:

I've used it once or twice and have initial impressions

This is my 2nd Stages and the prices has dropped!! The power seems to correlate well with my normal numbers, although it was only 1 ride. My first one is on a BMC and this new one on a Lynskey. Love my Stages PM’s.
